There's a fantastic all-singing all-dancing program called Sibelius. It does everything, including tab for just about anything. Only snag: it costs about £300 (UK pounds), and the upgrade to the built-in scanner utility is another £250 or so. When I win the Lottery I'll buy it, meantime you can download a 30-day demo.

Sharpeye isn't bad, but doing it by hand is more accurate and probably less frustrating, even if it takes longer. Noteworthy is Utterly Brill - I've actually bought a copy (an Offer I couldn't refuse!), and TablEdit is very good too (I'm saving up for that at the moment). It has a lot of tabs you can download, and handles lots of different instruments (not just strings), even several at once.

It's well worth downloading the demo versions of these programs and trying them out - you can get adept very quickly. When you have, let us know what you think.

P.S. I ought to add that none of this is a substitute for learning to play an instrument!! Some very useful accessories, though.
